The European Court of Justice, the highest court in the European Union, is kind of on a roll lately. We already discussed how they outlawed generic ISP-side internet filters, and now, in an opinion (so it's not a ruling just yet), Yves Bot, an advocate-general at the Court, has stated that functions provided by computer programs, as well as the programming languages they're written in, do not receive copyright protection. The opinion is very well-written, and relatively easy to read and grasp. Note:Brilliant quote from a comment over at Hacker News: "Copyright makes you write your own code. Patents prevent you from writing your own code."

Actually you don't, since copying has added more money to the overall amount of money. Thus diminishing the value of money.

Well that happens anyways... even without you copying the bank account.

In that case the people would get a bit of the power of the financial system that is currently reserved to banks and governments. Possibly highlighting a flaw that exists within the current system anyways.

Though I guess you could also argue that when the copy is made you not only have a copy of my incoming transactions also my outgoing transactions. So suddenly everything I paid for in my live with my bank account has suddenly doubled.

My mortgage payments on my house would be doubled so I would instantly pay off double whatever I did before. Same with transfers to my savings account, etc.

So I might actually be very very happy with you making the copy I did not lose anything but I did suddenly double my net worth.

This could ripple through the system and making the effect of copy null. (or recursively and the value of money all together ?

So I think the actual effect will be far more complicated then to think that only devaluation of my money supply will happen.
